Job Description:

Does the opportunity to advance your career while supporting climate action with a growing company excite you? And are you in search of a hands-on role with plenty of variety and responsibility?

If you're ready for all of this and more, we've got an opportunity for you.

We're a boutique consulting firm dedicated to shining a light on how climate change impacts large organizations now and in the future, and advancing strategies to thrive. From government to industry, our work educates and equips our clients with the tools to identify climate risks and strategize climate resiliency so they can make smart business decisions and seize climate-related opportunities.

As our new Office Manager, your role will be equal parts technical wizardry and team support required by an experienced administrator and organizational diligence of an effective office manager to ensure our Yorkville office is running efficiently for the benefit of the team. You're passionate about tech, and you're excited for the opportunity to leverage that passion in a dynamic office environment for the benefit of our team and our combined impact at addressing the climate crisis.

We're looking for someone who's proactive and curious; you're always learning and looking for ways to apply that learning to make your life (and everyone else's!) easier and more impactful. Whether that means mastering some new applications or thinking about new ways to apply what you already know, you love the practical aspects of improving processes and making an impact.

Your tasks will include:

  • Being the primary in-office administrator and supporting our existing part-time executive assistant
  • Being radically responsible for daily office-management related activities including ensuring supplies are stocked, accepting deliveries, and welcoming visitors
  • Respond to queries by phone, email, and in person, directing queries to relevant departments and persons
  • Take and distribute meeting minutes
  • Edit/proofread a range of materials, including newsletters, presentations, etc.
  • Scan/file/retrieve documents using proven organizational strategies
  • Data entry and database management
  • Research and document review
  • Manage executive calendars, scheduling meetings, travel arrangements, etc.
  • Format documents and manage printing and collation of deliverables required in printed format
  • Continually seek out new software and processes to improve the
efficiency and impact of the team
  • You'll have opportunities to be creative and bring your own preferences and personality to this role. That's why you'll need to be more than just organized and efficient: the best in this role will bring confidence to every task, take initiative, and solve problems independently.
  • Working with Mantle
    This is a full-time permanent position, working Monday to Friday core business hours with flexibility. We offer a competitive starting salary of $55,000 to $75,000/year commensurate with your experience, as well as vacation.

    You'll also get to work with a group of talented and mission-driven co-workers in a highly collaborative, high-performance workplace. Team members are bonded by our commitment to meaningful, purpose-driven work, helping real-world decision makers and influencers engage with and respond to the climate crises.

    If you're as passionate as we are about working in a collaborative and impactful role, in an evolutionary organization, we would love to hear from you.
